Title: Process for producing iodine pentafluoride
IPC: C01B7/24
Filed: 1965-06-17
Abstract: IF5 is prepared by contacting F2 with an inert solvent (preferably IF5) containing dissolved I2, preferably in amount 0.1-2.0 wt. per cent, at 10-60 DEG  C. and at atmospheric pressure, the mole ratio F2: I2 being 5.0: 1 to 5.5: 1.  The process may be carried out continuously in an apparatus (Figure not shown) where IF5 may be drawn off from a tank 7 through iodine leech vessels 15, 16 to pick up I2 and passed through a reaction chamber 3 (e.g. of steel with Ni or glass helices) in countercurrent to F2 gas (contact time 15-60 secs.) and returned to tank 7 from which the new excess may be removed as product.  A clean-up vessel 5 containing I2 crystals converts any IF7 formed or excess F2 to IF5.  The I2 content may be metered automatically using photometers to measure the discoloration of the normally colourless IF5.

Abstract: 1,051,815. Ferroelectric capacitors. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 18, 1965 [June 30, 1964], No. 25822/65. Headings H1K and H1M. The body of ferro-electric material constituting the dielectric in the capacitor shown is formed by applying a layer 13 of a first ferroelectric material to the base electrode and firing, then applying a layer 14 of another ferro-electric material having a different Curie temperature and firing again under controlled conditions to limit diffusion between the layers to an interlayer 16 which fuses the layers together. Since the layers 13 and 14 retain their separate identities, the dielectric constant of the composite body is approximately the mean of those of the individual materials and may be relatively independent of temperature over a selected range at least. Fig. 2 (not shown) illustrates the variation of dielectric constant with temperature for (A) a barium titanatestrontium titanate system containing 74% BaTiO 3 ; (B) a similar system containing 88% BaTiO 3 ; and (C) the composite structure of the invention employing equal amounts of (A) and (B).

Abstract: 520,993. Testing for combustible gases ; electric tests. MINE SAFETY APPLIANCES CO. Sept. 6, 1938, No. 26037. Convention date, Aug. 9. [Class 1 (i)] [Also in Group XXXVI] Apparatus for testing gases for combustible constituents comprises a Wheatstone bridge circuit having in one branch a testing filament, e.g. of platinum coated with catalytic material, arranged to be heated to a temperature causing combustion of the combustible constituents, and in a parallel branch a compensating element of considerably higher resistance so that the filament may be operated by a dry battery, changes of current due to combustion being indicated by an ammeter &c. To avoid the necessity for separate adjustment of operating voltage and bridge balance, the compensating element may have characteristics similar to but not identical with those of the testing filament, the arrangement being such that adjustment of a single rheostat in the battery circuit zeroizes the instrument at the correct operating voltage for the filament. As shown in Fig. 3, the testing filament 19, in series with a resistance 25, is balanced by a compensating element comprising a resistance 27 and ballast lamp 28, in series with a resistance 26 ; a single rheostat 32 controls both bridge balance and operating voltage. The apparatus, Fig. 2, comprises a case 10 divided by a partition 11 into an upper compartment housing the combustion cell 12 which is connected by pipes 13, 15 to a gas inlet 14 and hand pump 16 respectively, and a lower compartment housing the dry battery 44. In use, the apparatus is zeroized, in air, with the aid of a milliammeter 33, by adjusting resistance 32 by knob 32a. The pump 16 is then operated to draw suspected air through the cell 12 and the highest reading of the ammeter noted.

Abstract: 1,029,757. Discharging liquefied gas. LINDE A.G. July 2, 1963 [July 5, 1962], No. 26134/63. Heading F1R. Liquefied gas in a tank 1 is forced therefrom into a collecting vessel 3 by vaporizing a portion of the gas in the tank at a temperature slightly above that of the liquid in the tank. Part of the vapour from the vessel 3 passes to a storage container 17 and the remainder passes through a heat exchanger 5, compressor 7 and heating element 9 before returning to the vessel 3. Liquid from the vessel 3 is pumped into a storage tank 21 and safety valves 14, 23, 26 prevent excessive pressure build-up in the liquid and vapour circuits. In an alternative embodiment the heater unit may be located in a separate circuit using a condensible gas. In a further embodiment some of the liquefied gas may be vaporized and the vapour directly introduced into the tank to force out the liquid. The vapour may be cooled by being introduced beneath the lowest liquid level in the tank. Valve 11 is a throttle valve and by regulating the flow through the heater 9 maintains a constant pressure at the bottom of the tank 1.
